Apple today refreshed both the iPad Air and the iPad Mini lines with basically just refined specs but not a re-design or groundbreaking update. The iPad Air 2 is adding the 120fps 720p slow motion feature first seen on the iPhone 5s and bettered in the iPhone 6. However the iPad is not as generous as the iPhone 6’s 240fps and only sports half the frame rate.
Furthermore the iPad Mini 3 has no slow motion feature and seems the least refreshed tablet. If you want an iPad Tablet this year then the iPad Air 2 is a better option overall. If you just got an iPhone 6 or 6+ then both iPad models will be downgrades in performance and features except for the larger screens. For slow Motion the iPhone 6 is still the best bet for Apple products continuing forward.
